OK, in a basement with a poured concrete slab floor and 2 x 10 floor joists above.
I hung a laser level about 5 feet above the slab and set a story stick flush on the floor below each joist and marked the distance for each of the six joists I am going to build under. Then measured each mark to determine the following distances from the floor: 65.31" 65.50" 65.56" 66.00" 65.88" 66.25"
I am going to build a wall section out of 2 by 4's and I want the top plate to be level (as I can get it) and support the six joists, above. I will have a bottom plate of treated 2 x 4 and a top plate of the same material. I will nail my studs in place so that, when this short wall section is in place, each stud will line up with the respective joist above.
I determined that I wanted a height of 84 5/8ths inches for the wall section from bottom of bottom plate to top of top plate and now need to adjust the lengths of the studs to attempt to compensate for the uneven concrete floor.
I determined the difference for each stud and calculated the average distance, then subtracted the average distance from each measurement, above, and came up with -0.44" -0.25" -0.19" 0.25" 0.13" and 0.5" respectively.
Now, do I subtract the results from or add them to a length to achieve my objective?
